    Error Code: 3F0 appearing on boot


    Whenever I turn my computer on, I get a pop up box referencing an "error occurred."

    Screenshot here.

    The error says:

    File: Window.cpp
    Line: 44
    Error Code 3F0
    Message: An attempt was made to reference a token that does not exist

    Does anyone know what could have caused this error, and how to make it go away?

    Download and run ProcessExplorer. It does not need to be installed.

    Drag-and-drop target to find an image. If you're not sure which application corresponds to which image in Process Explorer, click and drag the little gun sight icon on the Process Explorer toolbar, and drop it on any visible window to find out what process/image it is.


    Once the error message is on the screen, start ProcessExplorer and drag the target icon and drop it on the error message window. It will show the process that generated that window highlighted in blue in the PE window.

    Can you boot the computer in Safe Mode?

    Thankyou Ztruker, it was a program starting on boot that was causing the error message - uninstalling the program has now fixed the problem. :)
